摘要(Abstract)：The talk is focused on tests of Einstein's theory of general relativity versus alternative theories of gravity with gravitational waves that are detectable by ground-based interferometers. Einstein's gravity theory has been greatly constrained in the quasi-linear,quasi-stationary weak field regime, where gravity is weak and velocities are small. Gravitational waves allow us to probe a complementary, previously unexplored strong field regime: the non-linear and dynamical extreme gravity regime. Such a regime is,for example,applicable to compact binaries coalescing, where characteristic velocities can reach fifty percent of the speed of light and gravitational fields are large and dynamic. This talk starts with the theoretical basis and a brief description of the detectors, including both gravitational-wave laser interterometers and bar detectors,leading to a discussion of the gravitational wave data detected and gravitational-wave tests using compact binary systems. It ends with a description of the first gravitational wave observations by advanced LlGO and the tests that can be performed with them.
